This one I can sort of answer. The following process has worked for me on a U10 with an external drive: 1. At the 'ok' prompt, type in the command-- show-disks 2. It will show the disks and ask you to select the one you want. Select the external drive (They are labeled a, b, c, etc. You should see a & b; pick the one corresponding to your external drive. If it's not obvious from the disk name, by using brute force you can do this twice, once with the external drive on and once not.) 3. boot ^Y (Ctrl-Y), or 'devalias gentoo ^Y' and then 'boot gentoo' If this doesn't appeal, you can wait for someone who actually knows the easiest way to do this on a U5 & then do that. At some point, you probably want to go to and grab some OpenBoot documentation. Somewhere on Sun's site is the answer to your exact question, but I haven't any idea where, anymore. Something else you can do is go to the #gentoo-sparc FreeNode IRC channel and ask around there.
